Additional instructions for adjusting or replacing the rear power window

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2005 Porsche 911, 2004 Porsche 911, 2003 Porsche 911, 2002 Porsche 911, and 2001 Porsche 911. However, it is still accessible from the selected car via links, so may be relevant.

The rear power windows can be operated:
- If the convertible-top is closed.
- If the ignition is switched on.
- If, after the ignition is switched off, the ignition key is not removed from the steering lock.
- Between switching off the ignition and opening a door for the first time.
- If a door is open; U.S. vehicles do not have this function.

Standardizing the system
The system must be re-standardized after an interruption in the power supply to the power window electronics. To do this the convertible top must be closed. Position-controlled lowering with convertible-top actuation and enabling for "automatic start-up" of window closing and opening are redefined. The standardisation process is initiated by continuous actuation of the operating button in the "Close window" direction. To do this, the convertible top must be closed or the hardtop must be fitted. The button must be held until the window is closed and is switched off by the blockage detection function of the power windows.
Blockage detection function
If the window drive encounters resistance when activated, the motor is switched off after a delay of 500 ms. If the rocker switch is pressed again within 10 seconds, the side window closes the power window with all of its closing force. The anti-crushing protection is deactivated.
